Abstract

See full text

A disclosed dilute copper metal composition has 57-85% wt Cu, ≥3.0% wt Ni, ≤0.8% wt Fe, 7-25% wt Sn and 3-15% wt Pb. A process includes partially b) oxidizing a black copper composition to obtain a first copper refining slag and a first enriched copper metal. The process further includes oxidizing h) the first enriched copper metal to obtain a second copper refining slag, whereby at least 37.0% wt of the amount of tin and lead processed through steps b) and/or h) is retrieved in the first and second copper refining slags together, partially reducing c) the first copper refining slag to form a first lead-tin based metal composition and a first spent slag, adding the second copper refining slag to the first lead-tin based metal composition thereby forming a first liquid bath, partially oxidizing d) the first liquid bath, thereby obtaining the dilute copper metal composition.
